10-15% of aquatic plants and hidden objects are planted shallowly at the edge of the pond to create an environment for lobsters to inhabit and shell and reduce mutual killing. The influence of water quality on lobster yield cannot be ignored. During the breeding process, the PH value of the pool water is kept between 7.5 and 8.5, and the transparency is 30-40cm. Fresh water should be added frequently, quicklime solution should be splashed regularly, water quality should be adjusted, and diseases and shelling failure should be prevented. 2. Feed feed reasonably. Lobsters will kill each other when hungry and under-fed, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feeds are wheat, aquatic plants, rapeseed cakes, etc. Animal feeds are miscellaneous fish, miscellaneous meat, livestock viscera, etc. At ordinary times, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters falling in the day and coming out at night and the density of lobsters in the pond. 3. Scientific fishing. Young shrimps can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed. The seedlings will be released in March and will be caught in rotation around June, selling large ones and keeping small ones.　　人人街上有家不起眼没招牌的租书店，陆续聚集了四位鲁蛇：最不会讨债的黑道小弟 – 张亮、生意惨淡的租书店老板 – 周广侠、宁愿负债也要拜金的 – 康乐佑、渴望被爱的富二代 – 丁邵恩《LORD of VERMILION 红莲之王》是由Asread与tear studio联合制作，改编自Square Enix旗下的同名卡牌MOBA类游戏的电视动画，是游戏系列迎来10周年之际的动画作品。Next, you will write various state classes.
